微信servlet开发

 

一、web.xml中注册servlet类

<!--微信信息拦截 -->
 <servlet>
  <servlet-name>wxServlet</servlet-name>
  <servlet-class>com.outsource.weixin.client.servlet.WxServlet</servlet-class>
 </servlet>
 <servlet-mapping>
  <servlet-name>wxServlet</servlet-name>
  <url-pattern>/wxServlet.php</url-pattern>
 </servlet-mapping>

 

二、处理业务的servlet类

package com.outsource.weixin.client.servlet;

/**

  *微信信息控制层

*/

public class WxServlet extends HttpServlet {
 private static final long serialVersionUID = -2776902810130266533L;

 // 自定义 token
 private String TOKEN = "weixin_kz";
 
 public static String wsUrl="http://115.29.49.7";

 private WxService wxService;
 private StatUserService statUserService;

 @Override
 public void init() throws ServletException {
           super.init();
           ServletContext servletContext = this.getServletContext();    
           WebApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(servletContext);    
           wxService = (WxService)ctx.getBean("wxService");
           statUserService = (StatUserService)ctx.getBean("statUserService");
 }
